Vl-evatom

A single item in an event control list.

This is a product type introduced by defprod.

Fields

type — vl-evatomtype-p: Kind of atom, e.g., posedge, negedge, edge, or plain.
expr — vl-expr: Associated expression, e.g., foo for posedge foo.

Event expressions and controls are described in Section 9.7.

We represent the expressions for an event control (see vl-eventcontrol-p) as a list of vl-evatom-p structures. Each individual evatom is either a plain Verilog expression, or is posedge or negedge applied to a Verilog expression.
